Detailed Description

The following describes the present invention in further detail with reference to the following examples and the accompanying fig. 1-4. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

As shown in fig. 1, the present invention includes a first supporting disk 10 and a second supporting disk 20, the first supporting disk 10 is fixed with the second supporting disk 20 through a supporting rod 70, a portion of the first supporting disk 10 is overlapped on a portion of the second supporting disk 20, a supporting rod 70 is provided on an inner wall of an arc section of an outer side of an arc section of the first supporting disk 10 overlapped with the second supporting disk 20 and an arc section of the second supporting disk 20 far from the overlapped portion, a creel 30 for sleeving a creel is provided on each of the first supporting disk 10 and the second supporting disk 20, the creel 30 of the first supporting disk 10 and the second supporting disk 20 is initially sleeved with the creel, the yarn on the first supporting disk 10 is used first, when the yarn on the first supporting disk 10 is used up, the yarn on the second supporting disk 20 is reused, and at the same time, a new creel can be replaced on the creel 30 on the first supporting disk 10 for standby, when the yarn on the second supporting disk 20 is used up, the first support disc 10 is replaced and so on.

As shown in fig. 1 and 2, since the first support disc 10 and the second support disc 20 are both high and the creel 30 is inclined upward on the first support disc 10 and the second support disc 20, there is a difficulty in exchanging yarns for the first support disc 10 and the second support disc 20, the creel 30 on the first support disc 10 or the first support disc 10 is connected thereto through the connection mechanism 40, the connection mechanism 40 includes a spring 90 and a buckle 100, one end of the spring 90 is connected to the creel 30, the other end is connected to the first support disc 10 or the second support disc 20, the buckle 100 is bent, one end of the buckle 100 is clamped to the first support disc 10 or the second support disc 20, the other end is fixed to the creel 30, when a yarn bobbin is hung on the creel 30, the buckle 100 is clamped to the first support disc 10 or the second support disc 20, when a new yarn bobbin is to be exchanged after the yarn on the bobbin is used up, the buckle 100 is released from the first support disc 10 or the second support disc 20 (the height of the first support disc 10 and the second support disc 20 is lower than the top end of the creel 30, so the replacing manner is more labor-saving than the traditional replacing manner), but because the spring 90 is connected, the creel 30 is hung on the first support disc 10 or the second support disc 20, the creel falls down, then the creel is sleeved on the creel 30, the limiting device 31 on the creel 30 is adjusted to be in a limiting state, and the buckle 100 is clamped on the first support disc 10 or the second support disc 20 again.

As shown in fig. 3, preferably, a V-shaped clamping head is arranged at one end of the buckle 100, which is clamped with the first support disc 10 and the second support disc 20, the material adopted by the buckle 100 is plastic, the insertion hole 12 is arranged on the first support disc 10 or the second support disc 20, the clamping head is matched with the insertion hole 12, the V-shaped clamping head is more easily inserted into the insertion hole 12 because the front end is relatively sharp, the tail end is easily extruded and deformed, and the original shape is rebounded after the V-shaped clamping head is inserted into the insertion hole 12.

As shown in fig. 2, the free end of the creel 30 is provided with a limiting device 31 for preventing the bobbin on the creel 30 from falling, the limiting device 31 includes a first limiting wing 31a and a second limiting wing 31b, the first limiting wing 31a and the second limiting wing 31b are respectively hinged to two sides of the free end of the creel 30, the lengths of the second limiting wing 31b and the second limiting wing 31b are both equal to the diameter of the creel 30, when the bobbin is sleeved on the creel 30, the bobbin can be limited only by turning the first limiting wing 31a and the second limiting wing 31b towards the outer side of the radial surface of the creel 30, and the directions of the two limiting wings are just opposite, and the bobbin cannot fall off when the creel 30 is fastened to the supporting disc. When the yarn cylinder needs to be taken down, the inner sides of the radial surfaces of the two limiting wing yarn inserting frames 30 are turned over.

As shown in fig. 4, the first supporting disk 10 and the second supporting disk 20 both fix a weft accumulator 50 through a fixing rod 60, the shape of the fixing rod 60 is a semicircular arc, the peak point of the fixing rod 60 is connected with the weft accumulator 50, two free ends of the fixing rod 60 are fixed with the first supporting disk 10 through fasteners, the weft accumulator 50 on the yarn conveying device is utilized to better output yarns while controlling tension, the weft accumulator 50 is connected with a broken yarn detecting device 80 through an L-shaped plate 81, a detecting port is arranged on the broken yarn detecting device, the side where the yarn outlet is arranged on the weft accumulator 50 is opposite to the side where the yarn outlet is arranged on the broken yarn detecting device 80, an infrared sensor is arranged on the detecting port, and the broken yarn detecting device on the weft accumulator 50 is utilized to detect the yarn outlet 80, so that the radial detection of the yarns can be efficiently and accurately performed, and the normal operation of the seamless knitting machine is ensured.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications and variations can be made in the embodiments or in part of the technical features of the embodiments without departing from the spirit and the scope of the invention.
